Profile: Uehling Instrument Co. specializes in custom creation of liquid level gauges. We also deal with ultrasonic/pressure switches, panel mounted gauges and alarms with either digital or analog displays. The digital Tank-O-Meter® measures tank contents regardless of the tank location in relation to the digital display. It is based on hydrostatic principle, and determines proper ratios in the mixing process. Our float switches are used to trip high/low level alarms, engage relays, control or start/stop pumps and open/close valves. They are furnished with level alert alarm systems to provide an audible, visual and relay output response to high/low & other alarm conditions.
